[0002] The occurrence structure of tungsten ore has changed from wolframite-based to scheelite-based resource structure. In the tungsten smelting process, the tungsten concentrate alkali decomposition process is widely used in the tungsten industry due to its stable process, adaptability to various complex ores, and high tungsten recovery rate. How to leach scheelite at low cost, low pollution, and low wastewater treatment is the focus of the tungsten industry, which has very important practical significance.

[0003] Industry researchers have proposed using hydrochloric acid to decompose tungsten concentrate to obtain solid tungstic acid and waste acid solution. Ammonium tungstate solution is obtained after ammonolysis of tungstic acid. The pure ammonium tungstate solution obtained by removing impurities such as phosphorus, arsenic, and silicon with magnesium salt can be used to prepare ammonium paratungstate products after evaporation and crystallization.

Tungstic acid and acid leaching solution are obtained by cooling and filtering.

[0007] S2. Regeneration and closed-circuit utilization of acid leaching solution

[0008] Add sulfuric acid to the acid leaching solution for incomplete calcium precipitation. The volume of sulfuric acid added is 0.1-2.5% of the volume of the acid leaching solution.

[0059] Specifically, the inner wall of the first material cavity 21 is rotationally provided with the rotating roller 31, and the side wall of the rotating roller 31 is uniformly provided with four material plates 32 along the circumferential direction of the rotating roller 31, and the surface of the material plate 32 forms a loading part a32 for loading tungsten ore; a discharging part a3 is formed below the loading part a32, and the discharging part a3 is in communication with the discharging port a2; the outer wall of the discharging frame 2 is provided with the limiting structure 33, which is used to limit the rotation of the rotating roller 31 in the circumferential direction; when the tungsten ore on the loading part a32 reaches the maximum weight, the limiting structure 33 is automatically unlocked, so that the rotating roller 31 rotates and the tungsten ore on the loading part a32 is dropped into the discharging part a3.

[0060] Specifically, the limiting structure 33 comprises a telescopic rod 331, a limiting ring 332, a rolling ball 333, and an elastic member 334.

[0065] Preferably, the rotating wall a35 forms a rotating surface which is attached to the outer wall of the metering barrel 34; the part of the rotating wall a35 which is close to the container box forms a flow guide portion a352 which is connected with the feeding portion a34; the part of the rotating surface which is located between the adjacent two feeding portions forms a liquid outlet portion a353 which penetrates into the leaching groove a1; in this way, in the state that the rotating shaft 341 is stationary, the leaching agent can enter the metering barrel 34 without leakage; when the rotating shaft 341 rotates, the feeding portion passes through the liquid outlet portion a353, so that the leaching liquid in the metering barrel 34 is guided into the leaching groove a1, realizing automatic discharging.

[0066] Preferably, in the initial state, the volume of the metering barrel 34 and the volume of the maximum carrying capacity of the carrying portion a32 are in the ratio of 2.1:1 mL / g or 3.1:1 mL / g or 4.2.1:1 mL / g or 5.2.1:1 mL / g; in this way, when discharging, the solid-liquid ratio of the tungsten ore and the leaching agent can be ensured, and the leaching effect is improved.

[0069] Specifically, the rotating roller 31 is formed with a pressure pipe 41 with normal pressure gas, one end of the pressure pipe 41 is movably arranged with the telescopic rod 331, and the other end is movably arranged with the piston block 42; specifically, the piston block 42 is rotatably arranged with a first threaded rod 43, and the first threaded rod 43 is threadedly connected with the pressure pipe 41; rotating the first threaded rod 43 can drive the piston block 42 to move in the pressure pipe 41, so as to adjust the air pressure in the pressure pipe 41; the greater the air pressure in the pressure pipe 41 is, the greater the weight of the load part a32 needs to offset the friction force; so more tungsten ore needs to be added; the setting in this way realizes the adjustment of the weight of the tungsten ore.

[0070] Specifically, the adjusting block 44 is movably arranged in the metering barrel 34, and the volume in the metering barrel 34 can be changed with the movement of the adjusting block 44; more specifically, the end of the adjusting block 44 is provided with a second threaded rod 45; the second threaded rod 45 and the first threaded rod 43 are connected through a synchronous belt, so as to facilitate synchronous adjustment of the solid-liquid ratio.
